[0002] With the development of medical technology, hospital beds have gradually evolved from equipment that can only be used for patients to lie down to multifunctional medical equipment. The existing flippable electric hospital beds have different body position adjustment functions according to the patient's treatment requirements. Its core goal is to assist medical care operations and improve the comfort of patients in bed.

[0003] During treatment, patients often need to be turned sideways according to treatment needs and their body positions adjusted to facilitate treatment and operation by medical staff. In order to facilitate patients to turn sideways, scientific and technological personnel have developed a bed that can assist patients in turning sideways.

[0017] Compared with the prior art, the advantages of the present invention are as follows:

[0018] 1. By providing a transfer blanket on the bed body, the transfer blanket can be transferred by the rotation of the winding shafts on both sides of the bottom of the bed body and drive the patient lying on the transfer blanket to move horizontally. Specifically, when the patient needs to be turned over and moved, the two groups of winding shafts can rotate synchronously to drive the transfer blanket to move, and transfer the patient to a side area of the bed body. This area deviates from the center of the bed body. At the same time, the lateral positions of the power shaft and the lifting assembly can be synchronously adjusted by the transmission of the screw assembly, and the power shaft and the lifting assembly are moved below the flip plate at the bottom of the patient.

[0019] 2. By providing an ejection assembly and an unlocking assembly at the bottom of the bed body, when the flip plate is flipped, its side and the arc-shaped plate can squeeze the driving wedge block in the positioning chute on one side of the bed body, squeeze the driving wedge block into the positioning chute, and cooperate with the transmission action of the transmission wedge block and the ejector rod to drive the elastic telescopic shaft rod located at the bottom of the bed body to elongate, so that both ends of the elastic telescopic shaft rod are respectively in transmission connection with the winding shaft and the power shaft. When the power shaft rotates to drive the lifting assembly to rotate the flip plate, the corresponding side winding shaft can be driven to rotate synchronously, realizing the feeding of the transfer blanket and avoiding the problem that the transfer blanket is damaged due to being pulled when the flip plate rotates.

[0028] The technical solution of the present invention will be further described in detail below in conjunction with the specific implementation mode.

[0029] As Figure 1 , Figure 2 , Figure 3 and Figure 5 shown, in the embodiment of the present invention, a multifunctional electric hospital bed that can be turned over laterally includes a bed body 1. The bottom of the bed body 1 is supported by support legs 2. A communication opening is provided in the center of the bed body 1. Two flip plates 4 are rotatably installed in the communication opening. The near sides of the two flip plates 4 are rotatably installed in the communication opening through a connecting shaft. A transfer blanket 3 is laid on the upper side of the bed body 1. One winding shaft 5 is installed at the bottom of each side of the bed body 1. The two winding shafts 5 are used to wind the two sides of the transfer blanket 3. The ends of the two winding shafts 5 are coaxially connected to two corresponding drive shafts 6 provided on one side of the bed body 1 through a meshing tooth disc group 23. The two drive shafts 6 are arranged at the bottom of the side of the bed body 1 where no winding shaft 5 is installed, and the two drive shafts 6 are connected by a first drive belt 7. The end of one of the drive shafts 6 is connected to a screw assembly provided at the bottom of the bed body 1 through a bevel gear group. The screw assembly is used to drive two sliding tables 11 at the bottom of the bed body 1 to linearly slide. The two sliding tables 11 are respectively slidably installed on the two sides of the bed body 1 where no winding shaft 5 is provided;

[0030] A power shaft 8 is rotatably installed between two sets of sliding tables 11. A lifting component 9 is installed on the power shaft 8. The corresponding connected turning plate 4 is supported and turned by the lifting component 9. A set of sliding plates 20 are respectively installed on both sides of the sliding table 11. A set of elastic telescopic shaft rods 14 are rotatably installed on the two sliding plates 20 in a mirror image manner. The proximal ends of the two elastic telescopic shaft rods 14 are drivingly connected to the power shaft 8 through a transmission component 10. The other end of the elastic telescopic shaft rod 14 is coaxially installed with a first bevel gear 25. The first bevel gear 25 can be engaged with a second bevel gear 26 at the end of the winding shaft 5. A jacking component 19 is arranged on the bed body 1 near the communication opening side;

[0031] When the turning plate 4 is driven by the lifting component 9 to turn upwards, the transmission drives the jacking component 19 to extend out of the bed body 1, and drives the elastic telescopic shaft rod 14 to extend so that the first bevel gear 25 at its end is engaged with the second bevel gear 26. At the same time, the unlocking component 15 on the sliding plate 20 unlocks the meshing tooth disc group 23, so that the winding shaft 5 is disengaged from the driving shaft 6.

[0032] As Figure 3 and Figure 4 shown, in the embodiment of the present invention, the meshing tooth disc group 23 includes a fixed tooth disc 2301 and a movable tooth disc 2302. The fixed tooth disc 2301 is coaxially installed at one end of the driving shaft 6 close to the winding shaft 5. The movable tooth disc 2302 is linearly slidably installed on the corresponding end side of the winding shaft 5 and is elastically connected to a fixing plate arranged on the shaft body of the winding shaft 5 through a return spring 1502. In the present invention, when the turning plate 4 is not turned, at this time the two turning plates 4 are in a horizontal state, the unlocking component 15 is disengaged from the meshing tooth disc group 23, and the driving shaft 6 and the winding shaft 5 are coaxially connected through the meshing connection between the movable tooth disc 2302 and the fixed tooth disc 2301. At this time, the two winding shafts 5 can be rotated to move the transfer blanket 3, and the patient can be displaced synchronously. The area of the transfer blanket 3 is relatively large and is in contact with the patient's body. At this time, the patient can be dragged to move by winding up the transfer blanket 3, which can minimize the harm to the patient during the transfer process.

[0033] As Figure 2 and Figure 4 shown, in the embodiment of the present invention, the screw component includes a driving screw 12 and a guide rod 13. The driving screw 12 and the guide rod 13 are respectively arranged on both sides of the bed body 1. Among them, the driving screw 12 is rotatably installed on the side of the bed body 1 without the winding shaft 5, and one end of it is drivingly connected to a set of driving shafts 6 through a bevel gear set. Its rod body forms a screw pair transmission with a set of sliding tables 11. The guide rod 13 is fixedly installed on the other side of the bed body 1, and it is in a limit sliding connection with the other set of sliding tables 11;

[0034] Furthermore, the bevel gear set comprises a main bevel gear 1 22 and a main bevel gear 21 which are meshed and connected. The main bevel gear 1 22 and the main bevel gear 21 are coaxially mounted on the ends of the drive shaft 6 and the drive screw 12, respectively. The drive screw 12 in the present invention is driven by the main bevel gear 1 22 and the main bevel gear 2 21 to be connected to the drive shaft 6, so that when the patient is moved by the transfer blanket 3 to a region biased to one side of the bed body 1, the two sets of sliding blocks 1503 are moved to the lower part of the patient by the rotation of the drive screw 12 and the guidance of the guide rod 13, and synchronously drive the power shaft 8 and the lifting assembly 9 to be connected to the flip plate 4 directly below the patient, so that the power shaft 8 and the lifting assembly 9 are synchronously positioned and moved in the process of the patient's displacement;

[0035] Further, such as Figure 2 and Figure 3 As shown, in the present invention, a first motor 17 is provided at the bottom of the bed body 1. The first motor 17 is installed at one end of the driving screw 12 to drive the driving screw 12 to rotate. Moreover, due to the transmission connection between the driving shaft 6 and the driving screw 12, the first motor 17 of the present invention can also be arranged and installed at one end of the driving shaft 6 to drive the driving shaft 6 to rotate.

[0036] like Figure 7 As shown, in the embodiment of the present invention, the lifting assembly 9 includes multiple sets of driving inner nuts 902, transmission rods 903, lifting blocks 904 and transmission slide blocks 905. The power shaft 8 is provided with external threads 901 for spirally connecting the multiple sets of driving inner nuts 902. One end of the multiple sets of transmission rods 903 is rotatably connected to the corresponding driving inner nuts 902, and the other end is rotatably connected to the corresponding lifting block 904. The upper end of the lifting block 904 is rotatably connected to the corresponding transmission slide block 905 at the bottom of the flip plate 4. The bottoms of the two sets of flip plates 4 are respectively provided with a set of limiting rails 906, and the two sets of limiting rails 906 can be rotated between the two sets of flip plates. The plates 4 are butt-jointed when placed horizontally. In the present invention, when the lifting assembly 9 lifts and flips the flip plate 4, the second motor 18 drives the power shaft 8 to rotate, and is driven by multiple groups of external threads 901 with different rotation directions on the power shaft 8, driving multiple groups of driving internal nuts 902 to move along the axial direction of the power shaft 8, and driving the lifting block 904 to move upward through the corresponding transmission rod 903. At the same time, during the movement of the lifting block 904, its rotatably connected transmission slider 905 can rotate synchronously with the flip plate 4, thereby avoiding the lifting block 904 from getting stuck with the flip plate 4 during the lifting process.

[0037] like Figure 3 and Figure 4As shown, in the embodiment of the present invention, the transmission assembly 10 includes a transmission shaft 1001, a second transmission belt 1002, a secondary bevel gear 1 1003 and two sets of secondary bevel gears 2 1004. The transmission shaft 1001 is rotatably mounted on the sliding table 11, and is transmission-connected to the power shaft 8 through the second transmission belt 1002. The secondary bevel gear 1 1003 is coaxially mounted on the transmission shaft 1001. The two sets of secondary bevel gears 2 1004 are respectively meshed and connected on both sides of the secondary bevel gear 1 1003, and are coaxially mounted on the ends of the corresponding elastic telescopic shaft 14. The present invention drives the rotation transmission of the power shaft 8 to the two sets of elastic telescopic shafts 14 by setting the transmission assembly 10, so that when the elastic telescopic shaft 14 is transmission-connected to the corresponding winding shaft 5, the power shaft 8 rotates, and while driving the lifting assembly 9 to lift the flip plate 4, the correspondingly connected winding shaft 5 can be driven to rotate, thereby delivering the transfer blanket 3.

[0038] Further, such as Figure 6 As shown, the ejection assembly 19 includes a movable cone wheel 1905, an ejection rod 1903, a transmission wedge 1902 and a driving wedge 1901. The movable cone wheel 1905 is coaxially installed at the end of the movable shaft 1401 in the elastic telescopic shaft 14. The ejection rod 1903 is vertically slidably installed in a connecting hole opened on the bed body 1, and its upper end is fixedly connected to the bottom of the transmission wedge 1902. The transmission wedge 1902 and the driving wedge 1901 are slidably installed in a positioning slide groove provided on one side of the connecting opening of the bed body 1. The transmission wedge 1902 is slidably connected to the inclined side of the driving wedge 1901. One end of the driving wedge 1901 is elastically connected to the side wall of the positioning slide groove through a supporting spring 1904, and the other side extends out of the positioning slide groove. The bottom of the flip plate 4 is provided with an arc plate 24, and the arc plate 24 is used when the flip plate 4 During flipping, the driving wedge 1901 is continuously pressed and limited. When the flip plate 4 is forced to flip upward, its side surface can be squeezed with the side surface of the driving wedge 1901, and the driving wedge 1901 is forced to retract into the positioning slot. At this time, the support spring 1904 is in an extruded state, and the inclined surface on the other side of the driving wedge 1901 squeezes the transmission wedge 1902, so that the transmission wedge 1902 moves downward, and drives the ejector rod 1903 to move downward. The bottom of the ejector rod 1903 acts on the inclined surface of the movable cone wheel 1905, squeezing the movable cone wheel 1905 and the movable shaft 1401 to move in the direction close to the outer side of the bed body 1, so that the first bevel gear 25 at the end of the movable shaft 1401 can mesh with the second bevel gear 26 at the end of the winding shaft 5, and the transmission connection between the power shaft 8 and the winding shaft 5 is realized through the elastic telescopic shaft 14;

[0039] Further, if Figure 4As shown in the figure, the unlocking assembly 15 includes a push rod 1504 and a movable cone pulley II 1501. The push rod 1504 is slidably mounted on a slide plate 20 through a slider 1503. The slide plate 20 is rotatably connected to a movable shaft 1401 of an elastic telescopic shaft rod 14. The movable cone pulley II 1501 is coaxially and fixedly mounted at the bottom of a movable gear disk 2302. When the movable shaft 1401 is driven by a jacking rod 1903 to displace outward from the bed body 1, the push rod 1504 located on the slide plate 20 can abut against the inclined surface side of the movable cone pulley II 1501 at the bottom of the movable gear disk 2302 and push the movable gear disk 2302 to move away from the drive shaft 6, so that the movable gear disk 2302 is disengaged from the fixed gear disk 2301. At this time, the winding shaft 5 and the drive shaft 6 are unlocked, and the winding shaft 5 can rotate independently of the drive shaft 6.

[0040] As Figure 1 shown, in an embodiment of the present invention, a heating wire is embedded in the transfer blanket 3. The heating wire is used to heat the surface of the bed body 1, so that when a patient lies on the bed body 1, the patient feels warm and the body temperature of the patient is maintained.

[0041] In summary, in the present invention, by providing a transfer blanket 3 on the bed body 1, the transfer blanket 3 can be transferred by the rotation of the winding shafts 5 on both sides of the bottom of the bed body 1, and drive the patient lying on the transfer blanket 3 to perform a lateral displacement. Specifically, when the patient needs to be turned over and moved, the two winding shafts 5 can be rotated synchronously to drive the transfer blanket 3 to move, and the patient is transferred to a side area of the bed body 1, which area deviates from the center of the bed body 1. At the same time, the screw assembly can drive the power shaft 8 and the lifting assembly 9 to synchronously adjust the lateral position, move the power shaft 8 and the lifting assembly 9 below the turning plate 4 at the bottom of the patient, and drive the turning plate 4 at the bottom of the patient to be driven and turned by the rotation of the power shaft 8, so as to push the patient to the other side and assist the patient in turning over;

[0042] At the same time, when the turning plate 4 is turned, the side surface and the arc-shaped plate 24 thereof are squeezed against the driving wedge block 1901 in the positioning chute, and the driving wedge block 1901 is squeezed and inserted into the positioning chute, and with the transmission action of the transmission wedge block 1902 and the jacking rod 1903, the elastic telescopic shaft rod 14 located at the bottom of the bed body 1 is driven to elongate, so that both ends of the elastic telescopic shaft rod 14 are respectively in transmission connection with the winding shaft 5 and the power shaft 8. When the power shaft 8 rotates to drive the lifting assembly 9 to rotate the turning plate 4, the corresponding side winding shaft 5 can be synchronously driven to rotate, realizing the feeding of the transfer blanket 3, and avoiding the problem that the transfer blanket 3 is damaged due to being pulled when the turning plate 4 rotates.

[0043] The above describes in detail the preferred embodiments of the present invention. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
